To all wi'wm it concern:

Be it known that I, CARL Gnnvirz, e. citizen'of the United States, residing at Day ton, in the county of /Vehster and State of Iowa, have invented certain new and useful Improvements in Interlocking Tile-Sections, of which the following is e, specification.

This invention relates to improvements in interlocking tile sections and more nerticnlarly to reinforced arcuete adapted to be assembled for forming relatively large conduits and similar cylindrical shepecl clevices.

The'primary object of the invention is provide a construction for an interlocking tile section of this character that Will efieetively reinforce the section and prevent col lapsingencl breaking of section while undergoing heavy strains and stresses.

Referring particular to rig. 5/3- of the drawing, it will be observed that the s comprises an outer convened Well 1 inner concev'etl Well 2 anti these the outer and inner wells, respecti lthe conduit when the ere The sides of the section are shaped to form the interlocking Walls 3 and each. of these walls includes the upper portion i: which lies in a plane in radial elinement with the {specification of Letters angle tor eoncmecl no cor ing too itch to the W inaterinlty e rial from lls and S integrally Jnetl with L the cenv tion. and 8 al o int which c111", iefl by one of the Wells 3.
